Loving the religion of Allah (may He be glorified and exalted), teaching it to the people, being angry and sad when people forget anything of it, and hastening to advise them and remind them, are all obligatory, and every Muslim must do them to the best of his knowledge and ability. The Sahabah (may Allah be pleased with them) were the keenest of people to do that. In this hadith, Umm al-Darda’ – whose name was Hujaymah; she was the younger Umm al-Darda’ and was a Tabi‘iyyah – narrates that her husband Abu’d-Darda’, whose name was ‘Uwaymir (or ‘Amir) ibn Zayd al-Khazraji, came in one day looking angry. She asked him why he was angry, and he said: By Allah, I do not recognize anything of the ummah of Muhammad (blessings and peace of Allah be upon him) except the fact that they pray together. In other words, he did not recognize anything that they were still adhering to of the teachings of Muhammad (blessings and peace of Allah be upon him) except their praying in congregation. He said that out of sorrow for what he saw of the people falling short in matters of religion. Undoubtedly this is a relative matter; the people of his time still adhered to most of the teachings of Muhammad (blessings and peace of Allah be upon him). Rather Abu’d-Darda’ was saddened by the difference between the Prophet’s era and what followed it, and undoubtedly there was a difference between the two, especially following the emergence of turmoil (fitnah) at the time of ‘Uthman (may Allah be pleased with him). Otherwise, their era was among the three best generations of which the Prophet (blessings and peace of Allah be upon him) said: “The best of humanity are my generation, then those who come after them, then those who come after them.” There is no contradiction between what Abu’l-Darda’ (may Allah be pleased with him) said and the Prophet’s prohibition on describing people as being doomed, as was narrated in Sahih Muslim from Abu Hurayrah (may Allah be pleased with him): “If a man says, The people are doomed, he is the most doomed of them.” The scholars are unanimously agreed that criticizing the one who says that people are doomed only applies to one who says that by way of looking down on people, thinking himself superior to them, and condemning what he sees of their situation, because he does not know what is in people’s hearts. As for the one who says that by way of expressing sorrow at what he sees in himself and in other people of falling short with regard to religious matters, there is nothing wrong with that. Moreover, Abu’l-Darda’ did not say, The people are doomed and have neglected religious matters. Rather he said it by way of comparing his situation at that particular time with the situation of the Sahabah at the time of the Prophet (blessings and peace of Allah be upon him). The Prophet (blessings and peace of Allah be upon him) had stated that no time would come, but what came after it would be worse. Narrated by al-Bukhari. This hadith indicates that it is permissible to be angry when there is a change in people’s religious commitment, and it is permissible to denounce evil by expressing anger, if one is not able to do more than that..
